How to use
Install the card into an available PCI or PCI-X slot on a powered-down computer, secure it to the chassis, and power on the system. Allow the operating system to detect the card and install drivers; if necessary, load vendor drivers compatible with the MosChip MCS9865IV-AA chipset for your Windows version. Connect RS-232 devices to the DB9 connectors, observing correct pinouts and verifying whether the peripheral requires the provided +5V/+12V supply. Configure COM port settings (baud rate, parity, data bits, stop bits) in the host application or device manager as required.
Usage recommendations
The card is intended for internal installation in desktop, thin client or server systems. Use shielded serial cables and secure chassis grounding for reliable communication in electrically noisy environments. Verify driver compatibility for your specific Windows version before deployment and confirm whether connected peripherals accept power from the DB9 connector to avoid accidental damage.
